Thermal break for a range hood vent?
I am about to install my range hood, a low cfm broan model I learned about on GBA, and will be using a luxury metals exterior vent, something I also learned about on GBA, and was wondering what I can do to reduce the thermal bridge between the exterior vent and interior hood. Normally one would use sheet metal btwn the two but this seems to create a very undesirable thermal bridge ripe for conducting undesirable temperatures in especially when it’s ten degrees outside. I have taken great pains to seal and insulate my house and am very happy with its performance, so I’d like to minimize what I presume will be a semi-significant thermal bridge. As always, thanks in advance for the advice,
